At the Outer end of the frame lo' is 'mdiinted a transverse bracket plate '22 ha v'ih'g *paed apart upright lugs 23""tji1etiti1ting h'gui'de and slide bearing fbr thfe ihiihfeeler 1Y1embe'r-'21 ;'which has extendihgqforwardly therefrom a 'rod 25 'slidibly gtided in its outer'end in an uptentlifig lhg 26 of the'bracket plate 22.

compression coil spring 27 is mounted on the rod 25 and having backing against the lug 26 engages a head 21 at the back of the main feeler member 24:, pressing it yieldingly rearward so that said head comes against the lugs 23, this being the normal rearward position of the feeler. A retaining plate 28 may 'be secured at the top of the lugs 23 as by a screw 29 to hold the main feeler member 24 from vertical displacement. In accordance with my invention a secondary feeler member formed as a small pin 30 with a pointedor knife edge extremity 30, is fitted to slide through the outer end of the main feeler member so that the pointed extremity 30 normally projects a little distance beyond the end of the main feeler member. The pin 80 is clamped in a socket 31 of a plunger 32 slidably fitted in the main feeler member, said pin being removably held in such socket as by a small transverse clamp screw as shown, so that said pin may be easily removed and replaced by another pin having a different size or character of pointed extremity, according to the varying requirements of difi erent kinds of filling; which it will be understood vary considerably as to fineness, degree of twist and character of winding. To further facilitate removal and replacement of the'pin 30, the main feeler member 2% isrecessed as seen at 33 adjacent its rearward end, affording a substantial finger opening so that the operator can easily reach'and remove or adjust the pin 30 whenever required. The plunger 32 is shouldered as seen at 32 so'as to limit the rearward movement thereof and it is yieldingly pressed rearward by a coil spring 34; encircling a rod projecting. from the. front of said plunger and reacting against an abutment of they main feeler which also serves as a forward guide for said rod; the front portion of the main feeler member being recessed as seeniat 35 to afford room for the housing of said spring and for the operation of the second ary feeler plunger 32. The plunger32 has operatively engaged therewith as seen at 36 the upper portion of a pin 37 rigidwith and extending upward from a short-shaft 38 transversely journaled in spaced apart lugs 39 depending from the main feeler member. The shaft 38 also has fixed at an outer projecting end thereof an upright plate arm 10, the upper end of which is notched as seen at 41. Cooperating with this plate and guided in the notch 41 is a trigger plate 42 rigid with and carried by an arm 43 which is pivoted at 44 to the head 24: at the front of the main feeler member, the arm 13 being a two-part construction with an interposed adjusting turn buckle 45 equipped with a clamp nut 16 whereby said arm may be adjusted as to length as required for its proper operation. The trigger plate 42 has its outer portion formed with a ledge 12" adapted to rest on and be supported by the plate arm 10 engaging the same at the bottom of the notch 41. Just back of the ledge 12* the trigger 42 is formed with a relatively deep notch 42 permitting said trigger and the arm 13 to drop some little distance when the arm 4C0 is swung slightly to disengage the ledge 12* from the bottom of the notch ll so that said trigger will then come to rest with the bottom of the notch 12 thereof engaging the bottom of the notch 41. A spring 17 anchored to the head of the back of the main feeler at 48 presses on the forward portion of the arm 43 to hold the ledge 4-2 normally pressed against the arm etO'and to accelerate the downward movement of the arm -13 when said trigger is tripped.

-The arm has a downward extension 43 with spaced apart inward projections 4-3 43 adjacent its lower end adapted to receive and hold between them the end of the arm extension 19 when the arm 43 drops downward as described; the depth of the notch 42 being such as to position said projections correctly for this purpose.

It may now be understood that in the normal operation of the loom the trigger 4:2;will be cocked, i. (3., with the ledge as resting on-the arm 10, and the penetrating point 30 'will be yieldingly held projected a smalldistance from the end of the main feeler member so that on the detecting beats of the lay, as the main feeler member passes through the slot S of the shuttle S, said penetrating point will press into the filling so that the main. feeler member 2st will be prcssed'back without any relative movement of the plunger 32 with respect thereto. As soon however, as the filling becomes substantially exhausted the penetrating point 30 coming against the relatively hard surface of the bobbin will be pressed inward on the detecting beat and this small movement transmitted through the relatively short arm 37 will turn the shaft 88 and swing the arm et-O so that the ledge 42 of the trigger 42 will drop off the arm 10 and permit the arm to 7 swing downward. The lower end of the arm 41-3? which has normally been held above the arm extension 19 so as to clear the same, is now positioned so. that the end of said'arm extension comes between the projections as, e52 thus as the main feeler member is pressed backward swinging the arm 19 upward and causing oblique concave edge 19 thereof to act as a cam swinging the arm extension 16 laterally and thus rocking the shaft 13 to operate the stop motion. The arm 43 which thus engages the arm 19 to lift it, is itself lifted as the main feeler member moves bflCl(\\21l'(l,S0 that the ledge 42 of the trigger is again lifted over the bottom of the notch ll in arm 40, whereupon the spring 3% again presses the penetrating point forward, and swings the arm L0 back torengage undentheledge 42",thus automaticallyresetting the. device [for an- {other operation. It will be observed that; the

stop motion in=this way; is notrset in operation immediately onthe-pressing back of the penetrating point 30?.av-ith respect to the main feeler, but that the main feeler is pressed back on this movement,-and= another full movement of the lay takes place before- 7 the arm 19 is lifted to operate the stop moonly a very small pressing back of the point 30 is necessary to operate the stop mechanism,.i. 6., just enough so that when multiplied by the lever connections described, the arm Will be pushed off the ledge 42, it

being understood that it only rests on. a

small corner of said ledge when in cocked position. 7 Thus the end ofthe main feeler may approach relatively very close to the bobbin core, 13. 6., removing all but a mini-' mum layer or so of thread before the point 30 is pressed back to operate the stop. In

this Way also the end of the main feeler member 24 may slip over the yarn with the penetrating point 80 offering a minimum of obstruction by reason of its relatively minute projection into the filling mass. The described construction and arrangement of the oscillating shaft 13 with the arm 19 will be reco nized as pertaining to the well known Sta ord loom type. For applying the invention to a loom of the Draper or similar type the arm 19 is equipped With an upstanding projection 49 which is adapted to cooperate with the stop mechanism of the Draper loom in a manner that will be readily understood. I am aware that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:
